FIELD OF THE TECHNOLOGY

This application relates to the field of cloud service technologies, and in particular, to a method for obtaining mobile terminal security information based on a cloud service, a terminal, a storage medium, and to a method for delivering mobile terminal security information based on a cloud service, and a server.

BACKGROUND OF THE DISCLOSURE

With the development of mobile terminal technologies and mobile network technologies, currently, mobile terminals have become necessary tools in people's daily life, work, and entertainment.

Various types of application software providing different services are installed in a mobile terminal, and some virus software may be hidden in the various types of application software installed in the mobile terminal. As a result, security detection needs to be performed on the mobile terminal to discover virus software.

Generally, security detection on a mobile terminal is manually triggered by a user, or security detection on a mobile terminal is set to be performed when the mobile terminal starts up, or is set to be performed every once in a while, for example, once a day. In each security detection process, the mobile terminal downloads latest security data such as a latest virus database from a cloud. Further, the mobile terminal locally detects whether software included in the virus database is installed, and generates a corresponding detection report.

However, security detection cannot be performed on the mobile terminal in real time, and there is always a delay of certain duration. Therefore, security detection cannot be performed on the mobile terminal in time with reference to the latest security data. Consequently, virus software may threat information security of the mobile terminal at a time interval between two times of security detection.

In an embodiment, the user information corresponding to the user account that is currently logged in the mobile terminal includes one or more than two of software setting information of the mobile terminal, suspected fraud numbers specified by a user, or a geographic area of the user. The software setting information is used for representing a software behavior allowed by the user, a software behavior prohibited by the user, and/or the like.

Step S204. Receive security information sent by the cloud, where the security information is generated when the cloud determines that a security risk exists in the mobile terminal, the generated security information is sent by the cloud to the mobile terminal, whether the security risk exists in the mobile terminal is obtained by the cloud through determining with reference to the mobile terminal information and latest security data of the cloud, and the determining step is triggered by updating of security data of the cloud.

The security information is used for describing the security risk that exists in the mobile terminal.

In an embodiment, when the security data of the cloud is updated, the cloud determines, with reference to the mobile terminal information and the latest security data of the cloud, whether the security risk exists in the mobile terminal.

In an embodiment, the security information received from the cloud includes related information of one or more than two of virus software that exists in the mobile terminal, a software dangerous behavior, an operating system bug, or the like, and is used for providing a basis for security protection of the mobile terminal information. For example, the security information includes virus software related information in the local software list of the mobile terminal, dangerous software behavior related information in the local software list of the mobile terminal, information about a bug that exists in a current version of operating system of the mobile terminal, patch software corresponding to the bug, and/or the like.
